Well gang, I just got of the phone with Rocco, from A/W. I
voiced my concerns and thoughts about the problem with
the stab on our 540 60/90 size. They have sent out over 250
planes so far, and their area alone, he has seen 10 of them flying. There have been only 2 of the problems with the horizontal
stab. Rocco himself has over 75 flights on the protoytpe, and
JUST RECENTLY changed the elevator servo from a ....get this...
Futaba 148. Same y-pushrod, same control wire. He changed
because of a little flex when doing blenders, and walls. So, he has put a newer/better/100 tq/ounce in it. Also has one flying
with 2 elevator servos. Rocco said the plane is designed to do
3d stuff, and do it well. He said in polite terms, and in all honesty,
that going on a down line, at full throttle, will tax any plane when
pulling hard on the elevator. He has done a lot of blenders and pop-ups, and walls, never any problems. But, like I do, he does
them at reduced throttle, then power when needed in the manouver. Down lines should not be done at full chat, then pull
up so hard. I agree with this, and Rocco also said that one of the
planes that had the problem did not have any gaps sealed, and the pilot tends to fly at full throttle the whole time. So, if you
are one of the all or nothing guys, Rocco said it would be good to
put some wires or pull/pull wires on the stab to beef it up. He will
be posting here as to how he did it, but it is simple. So, after building a few of their planes, and talking to them at various times, the info is good enough. Rocco said he has also seen some fly with a 4 channel radio, y-harness for ailaerons, set up with full 3d throws, no dual rates, and a aft c.g. Scary stuff. I will be putting my stab in tonight, won`t be bracing it, won`t cut, weld, or otherwise hack it apart. Only thing I will change is to put a
MK elevator bell-crank, so one servo does 2 pushrods for the elevators. Rocco siad he will try one of those too. So, sounds a bit snarkey here guys, but let`s just build the damn plane, keep it simple, don`t add or hack stuff from the plane, seal thye hinge gaps, keep the linkages tight, and see what she does. As for the full throttle stuff, and pulling HARD, get some braces on the back, or do what I do... fire up my Diamond Dust!!!
Sorry about the length, but ....
Take care everyone.
